Compute the structure factor for both the disordered and ordered states and determine which reflections are only present in the ordered state; these are known as superlattice reflections.
What is Superlattice Reflections?
A superlattice (SL) is a structure in which two different materials are grown in alternating layers to a specified thickness. home:
Nitride semiconductor light emitting diode (LED)
Therefore, Compute the structure factor for both the disordered and ordered states and determine which reflections are only present in the ordered state; these are known as superlattice reflections. Order and superlattice reflections: in the disordered state,Cu3aAuhas an fcc structure, with lattice parametera=0.3749Â nm. In the ordered state, Au occupies the corners of the cell, whereas the Cu atoms occupy the Gace centers. (Assume that the lattice parameter remains constant).

A Ghetto, was the location were Jews during the WW2 were marginated, as the expression of an anti-semitic racial policy of Adolf Hitler that became institutionalized.
Most of the Ghettos were established all over Germany, Poland, parts of France. There the conditions for a living were extremely bad: they lacked the most essential things for a living. Many didn't have good energy and water supply. The security of the neighborhood is also compromised. Many unrest can happen and there is little to be done as authorities will not care. As leaving a Ghetto was illegal, the people escaping them were systematically executed.
Perhaps the most representative Ghetto is the nowadays Warsaw Ghetto, that serves as museum and memorial for Nazi crimes against humanity. This Ghetto once had almost half a million people living on it.
Below you can see how many Ghettos mostly in East Europe were later transformed into Death Camps:
Answer:
Confederate Army Under Robert E. Lee Wins Second Battle of Bull Run (Manassas) ... After Confederate artillery turned back a Union attack on Jackson's positions, Longstreet ordered his corps forward in an aggressive counterattack on the Union left, which had been weakened after Pope shifted his troops right to hit Jackson
Explanation:
Any thing that contained vitamin C, such as an orange could not be taken aboard the ship without rotting in days or weeks. Either that or it would lose all its nutrients by then.
